In the 1950s America had broken free from the shackles of wartime economics. It was a time for innovation, when scientists learned to harness nuclear energy and jet-propelled airplanes were breaking speed records. Where scientific innovation met consumerism, the result was the concept car - a prototype made to showcase a concept, new styling and new technology. MYSTERY CARS is a fascinating series that finds these one-of-a-kind vehicles and tells their story.
